Processing Techniques

Every day people always produce household waste. In an average day each resident produces 2-3 liters of waste. To reduce the amount of waste that is disposed of in the TPA, the community needs to carry out their own waste processing techniques. The most appropriate method of processing organic waste is to use  the compost. Compost is an effort to process organic waste through a controlled  decomposition process. The main product of composting is environmental cleanliness, because the amount of disposing organic waste in the landfill that can be reduced. Subsequence, it can be obtained the compost yield as another advantage. Composting with the Takakura method is very suitable for tropical areas and household scale.

Market waste is the second largest waste after household waste. Vegetable and fruit waste is the largest organic waste that comes from market waste. Various waste management efforts have been carried out by the government and the community, but have not completely resolved the waste problem. The purpose of this study was to determine the effect of market organic waste processing using an earthworm reactor (Lumbricus rubellus) with a modified Continuous Flow Bin method on cocoon production, biomass, and exmecat. This study used an experimental method with a completely randomized design (CRD), with three treatments of a continuous flow bin modified three types of mixed media materials to increase cocoon production, biomass, and exmecat quality. The results showed that the type of reactor had a significant effect (P ≤ 0.05) on cocoon production, the amount of biomass, biomass weight, broodstock mortality, exmecat production, media temperature, and media humidity, but had no effect on media pH. The use of reactor 2 (R2) with a mixture of 50% horse feces + 50% rice straw + feed 50 grams / day / nest box for market organic waste is the best reactor compared to reactor 1 (R1) and reactor 3 (R3). The amount of organic waste that can be processed by earthworms (Lumbricus rubellus) either as a medium or as feed is an average of 4.35 kg / nest box for 40 days of cultivation with a stocking density of 25 grams of earthworms / nest box. Based on the results of this study, it can be concluded that the ability of earthworms (Lumbricus rubellus) to process market organic waste using the modified Continuous Flow Bin method can reach 4.35 times their body weight / day. Thus, this waste processing method can be a complete solution to solving market organic waste management problems.

Blockage of septic tanks is one of the problems in the community related to the discharge of toilet waste produced. The use of synthetic toilet cleaners that are not environmentally friendly is one of the factors that can inhibit the process of decomposing organic waste. The existence of microbial killer ingredients in toilet cleaning materials that come into the septic tank will actually inhibit the growth of essential microbes that play a role in the perfection of the decomposition process. Lack of understanding of the community related to microbial processes in the processing of toilet waste is one of the factors inability of the community to overcome these problems. This community service aims to disseminate information related to the processing of organic waste, the role of microbes in the processing of toilet waste, how to make microbial formulas that play a role in the processing of toilet waste, as well as efforts to increase the creativity of the community to process their own waste to improve environmental sanitation and improve community welfare. The results of the training showed that the average pretest and post test scores of the cadres of Tenggilis Surabaya village experienced a significant increase in value with a mean value of 37.78 (pretest) to 62.22 (post-test). Toilet waste processing cadres have been able to make biotoilet products that can be used to process limbat toilets in their homes. The informationand insights they receive can be passed on to the community from each cadre.AbstrakPenyumbatan septic tank merupakan salah satu permasalahan di masyarakat terkait dengan buangan limbah toilet yang dihasilkan. Penggunaan pembersih toilet yang berbahan sintetik yang tidak ramah lingkungan merupakan salah satu faktor yang dapat menghambat proses penguraian limbah organik. Keberadaan bahan pembunuh mikroba dalam bahan-bahan pembersih toilet yang ikut masuk ke dalam septik tank justru akan menghambat pertumbuhan mikroba esensial yang berperan dalam kesempurnaan proses dekomposisi. Kurangnya pemahaman masyarakat terkait dengan proses mikroba dalam pengolahan limbah toilet merupakan salah satu faktor ketidakmampuan masyarakat dalam mengatasi permasalahan tersebut. Pengabdian masyarakat ini bertujuanuntuk mensosialisasikan informasi terkait proses pengolahan limbah organik, peran mikroba dalam pengolahan limbah toilet, cara membuat formula mikroba yang berperan dalam pengolahan limbah toilet, serta upaya meningkatkan kreativitas masyarakat untuk mengolah limbahnya sendiri guna meningkatkan sanitasi lingkungan dan meningkatkan kesejahteraan masyarakat. Hasil pelatihan menunjukkan bahwa rerata nilai pretest dan post test kader kelurahan Tenggilis Surabaya mengalami peningkatan nilai yang cukup signifi kan dengan rerata nilai dari 37,78 (pretest) menjadi 62,22 (post test). Kader pengolahan limbah toilet telah mampu membuat produk biotoilet yang dapat dimanfaatkan untuk mengolah limbat toilet di rumah masing-masing. Informasi dan wawasan yang mereka terima dapat di teruskan kepada komunitas asal masing-masing kader.

High percentage of organic waste in urban areas makes composting as good alternative in waste processing. However, composting has not been effectively used and the result is not optimal. Previous studies found compost can be used as biocover media to reduce methane emission landfill. The objective of the study is to identify the characteristic of produced at temporary waste unit Depok, West Java and the effect of compaction toward the amount of methane removal in the landfill. Before applied as biocover media, compost was characterized followed by maturation process. Study on methane removal efficiency was conducted as batches in four reactors for 35 days with compaction rate varying from 750, 800, 850 dan 900 kg/m3. Composting media used in the research had 80 cm thickness with artificial gas consisting of 50% CH4 dan 50% CO2. Initially, compost did not meet criteria as mature compost based on SNI 19-7030-2004, and as media biocover hence a pre-treatment was needed to improve the quality compost to meet the requirements. Compaction rate of 900 kg/m3has highest elimination capacity of methane i.e. 98,31%±3,6% and 13,98±4,32 g/m3/hour.

Starting Point

The absence of accurate information on the state of waste is a challenge to the solid waste management system in Syria. The local authorities commonly estimate the quantity of waste produced and its characterisation, which is the starting point for solid waste management planning. So, this paper aims to evaluate the generation and composition of household solid waste in Homs city, Syria. Also, the study presents factors influencing the waste generation rate and the waste composition. The study was carried out in 300 families from four zones in Homs city, and three sampling stages were conducted during the study duration, which started in July 2017 and ended in February 2019. The outcomes show that an average of 0.68 kg/per/day solid waste generated was calculated for the entire study area in Homs city. Also, the data analysis presents that organic waste constitutes the largest component in the waste mixture (69.1%) followed by plastic (10.6%), inert materials (8.7%), paper (4.6%), textile (2.5%), metal (1.2%), glass (1.1%), wood (0.6%), and hazardous materials (1.6%). The multiple linear regression results showed that the adjusted R2 value was found to be 0.557, 0.839, and 0.709 for the waste generation per capita, the daily household organic waste generation, and the daily household packaging waste generation, respectively. Also, according to Pearson’s coefficient values, a positive correlation was found between household waste generation and monthly income (r = 0.626), household size (r = 0.37), and age of the household head (r = 0.517), whereas a negative correlation was found between household waste generation and the education level of the household head (r = −0.649).

EFFECT OF NUMBER OF METHANOBACTERIUM AND FERMENTATION DURATION TO METHANE (CH4) GAS PROPORTION IN ORGANIC WASTE PROCESSING IN SUWUNG TPA DENPASARA research has been conducted to find out the effect to the amount of methanobacterium bacteria and fermentation duration toward proportion of methana (CH4) at organic waste processing at TPA Suwung Denpasar. Methana gas produced from this organic waste will be processed become fuel of electric generation. From this study will be expected to get all methana gas that contained at the waste so that there is no methana gas loss to the atmosphere. This study was conducted by using 4 treatments that are without bacteria (B0), bacteria with number of population  106  CFU/ml (B1), bacteria with population of 107 CFU/ml (B2), and bacteria with population of 108 CFU/ml (B3). Each treatment conducted thrice (3) repeat. The four treatments conducted measurement of gas variable after fermentation during 0 week, 3 weeks, 5 weeks, 7 weeks and 9 weeks by uisng gas analyzer  GA 2000 Geotech. Data from study result then analyzed by using complicated factorial design (RAL). From ANOVA analysis shows there was significant bacteria number and fermentation duration toward proportion or procentage of methana gas resulted. The longer fermentation time takes place, the bigger the proportion of the methane gas produced.  However, the greater number of the bacteria population does not always produce bigger proportion of methane gas To find out the combination which could give best effect the researcher used Duncan test. The result of analysis from Duncan shows that combination at the ninth weeks by number of bacteria 107 CFU/ml giving best result that was percentage of methana gas is 55,10%.

Waste Generation Rate

Bhaktapur Municipality has been performing better to keep the city clean. However, scarcity of space for the land filling of the solid waste and proper segregation of waste at the source has been a hurdle for the Municipality. This paper aims to determine solid waste generation rate and to analyze overall situation of solid waste management of Bhaktapur Municipality. However, the data will not represent the seasonal and occasional variations. Additionally, waste from street-sweeping and large-scale institutional and commercial components of the Municipality has not been assessed. Arkin and Colton (1963) was referred for the sample size determination. Sample of 376 households were taken accordingly. Twenty representative samples each for commercial and institutional establishments were selected, and one each for special cases such as hospital, slaughter house and poultry has been assessed. Municipal household waste generation was found to be 0.093kg per capita per day which was chiefly composed of 77% organic, 18% plastic and 3% paper. Organic waste has been a major waste for institutions such as schools whereas at governmental and public offices, paper is the predominantly generated waste. Among commercial establishments, shops and restaurants mostly generate organic waste and that for departmental stores has been paper. Though collection system was found to be satisfactory, treatment and final disposal have been unsustainable. Available treatment facilities have been shut down whereas other infrastructural components have been lacking.
